For a project, I needed to display some numbers. There are of course a lot of different way to approach this, but a cheap (and presumably easy) way is to get some old fashioned 7 segment LED display modules.
The 7 segment LED displays literally consist of 7 LEDs arranged in a way where numbers can be displayed. From a random datasheet they are all arranged like this:
As is quite usual with me, I might (as can be seen on the photo to the right) have overdone it a bit and I managed to get 3 different types.
These modules are readily available and they are absolutely insanely cheap. Unfortunately, cheap usually means:
- Poorly Documented
- Some bizarre communications protocol
